I actually visited the ME-262 project while I was in Seattle, they run it out of a hanger on the same field as the Boeing Factory. They have a very small crew there working on these aircraft and the woman who showed us around was very nice and they are very open to people stopping by and poking their head around. THey don't do organized tours so you just kinda show up and ask to be shown around, no charge. If anyoen is in Seattle, I suggest you check them out...
Eclipse is still advertising a guaranteed price of $950,000 (with adjustments for inflation), but I think that when they actually start rolling production models out they'll have crept up substantially.
Diamond is claiming something like $850,000 for their single engine jet.
Cessna's $2.4M for the Mustang is probably a much more "realistic" price, though.
I can see the single engine D-Jet going for about 1.25-1.5 million, but not the Eclipse. Alot of their assumptions were flawed when they first announced the jet, and that price requires a substantial volume of production. I did see the airframe at NBAA in Orlando, and it looks impressive. I wish them well, but I can't really see how they are going to produce a twin jet for that price.
